Common issues
What should I check first?
Start with SPF, DKIM, DMARC, sender profile, bounce handling, and a conservative sending plan. Then review message content.
Where does Folderly Email Generator fit?
Folderly Email Generator drafts cold emails from offer, audience, and goal context. Folderly remains the deeper deliverability and inbox placement platform.
Should I rely on a single deliverability score?
No. Use scores as signals, then review authentication, sender reputation, content, audience quality, and mailbox behavior together.
